Abstract:
Although password authentication is the most widespread user
authentication method today, cryptographic protocols for mutual
authentication and key agreement, i.e., password authenticated key
exchange (PAKE), in particular authenticated key exchange (AKE) based
on a password only, are not actively used in the real world. This
document introduces a quite novel form of PAKE protocols that employ
a particular concept of ID-based encryption (IBE). The resulting
cryptographic protocol is the ID-based password authenticated key
exchange (I-PAKE) protocol which is a secure and efficient PAKE
protocol in both soft- and hard-augmented models. I-PAKE achieves the
security goals of AKE, PAKE, and hard-augmented PAKE. I-PAKE also
achieves the great efficiency by allowing the whole pre-computation
of the ephemeral Diffie-Hellman public keys by both server and
client.
